Gamma Revive Tennis Ball Pressurizer – Pressurized Ball Saver Storage Canister, Keeps Balls Fresh, Preserves and Restores New Ball Bounce

The original Revive Tennis Ball Pressurizer from Gamma! The pressurizer works by compressing atmospheric pressure between two cylinders to maintain 14 p.s.i. internal pressure when sealed, the same pressure inside your tennis balls when they are new. If left inside the Revive Ball Pressurizer long enough, a used ball will actually regain its original out-of-the-can pressure level. Never waste time or money on replacing your worn balls again! Holds up to 3 balls. Save them and keep them fresh in the Revive from Gamma!
